Currently hitting ^C prints out two stack traces, requiring scrolling up
though multiple screens of scrollback to get back to the autoupdate
results. This primarily shows up when hitting ^C while it's symbolizing
a C++ stack trace.
Trying to improve resilience against failures such as:

It looks like GitHub currently has a high rate of these, which it
shouldn't, but also maybe we can do a little more to weather these
service issues.
To show flag behavior:

I'm treating my PR to mypy bazel integration as dead in the water. Abandoning that approach, this seems to work reasonably well as a replacement. It's actually a slightly newer version of mypy too -- the bazel integration was stuck on an old version.
Note I don't think we're losing much: we shouldn't be writing too much python.
I went down this route because I figured the installer binary should be in `check_deps`. The result:
- Add thin wrapper scripts for `buildozer` and `bazel`, similar to the `buildifier` wrapper that's already there.
- These are mainly to avoid deduplicating logic, and dodging intricacies of Python imports that I don't understand well through instead subprocessing.
- Fix update_roots.py (it was missing a `.parent`, must've been relocated without a re-run at some point)
- Fix fuzzer proto code to be `testonly`
- Update the `check_deps` targets
